Millions of households across the UK are being urged to switch providers as the energy price cap is set to increase by up to £153 this October.

The Ofgem price cap acts as a safety net for over 15 million customers to make sure that they’re not paying too much for their energy. The cap is reviewed twice a year in line with the wholesale cost of energy to keep prices fair for both providers and consumers.

I appreciate this is extremely difficult news for many people, my commitment to customers is that Ofgem will continue to do everything we can to ensure they are protected this winter, especially those in vulnerable circumstances. - Jonathan Brearly, CEO at Ofgem

Who is affected by the price cap?

There are two groups of people who will be affected by the increase in Ofgem’s price cap: those who are on a Standard Variable Tariff (SVT) and those with prepayment meters.

At the end of your tariff, if you don’t switch, you’ll likely also be on your provider’s Standard Variable Tariff (SVT). This is often their most expensive option as prices can change regularly (usually in line with the Ofgem price cap). The new price cap for customers on SVTs paying by direct debit will increase by £139, bringing the cap to £1,277 per year.

Energy prices for customers with a prepayment meter are often more than those with a credit meter already, and this is set to be even more prevalent with an increase of £153 to the Ofgem price cap. Prepayment customers will see the price cap rise to £1,309 per year, compared to the previous £1,156.

The changes to the price cap will come into effect from the 1st October.

Higher energy bills are never welcome and the timing and size of this increase will be particularly difficult for many families still struggling with the impact of the pandemic. - Jonathan Brearly

Why is the energy price cap increasing?

Ofgem sets the price cap based on a range of factors, such as the wholesale cost of energy, network costs, policy costs, operating costs, and prepayment meter costs.

In the past six months, the wholesale cost of gas has risen by over 50%, reaching a record high across the whole of Europe. This is due to a recovery in demand after lockdowns and tighter supplies, increasing the cost of heating homes and even pushing up electricity prices.

How to avoid the new changes

To make sure you avoid increased bills due to the increased price cap, the best thing to do is to compare and switch tariffs and providers.

If you switch before the 10th September, you’ll be able to completely avoid the effects of the energy price cap changes. This is because the switching process takes around 3 weeks to complete so your switch will be finalised before the price cap increase comes into effect.
